I heard from christians and chuches that the gift of diversities of tongues was only for the apostles time. I don't believe that. But I don't understand what diversities of tongues really means for God.

The Bible said : And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues. 1 Corinthiens 12.28

I am christian and I believe in God's gifts. Why I don't speak diversities of tongues? What should I understand when Paul said he spokes diversities of tongues?
